Sqoop1.99.6 Install And From MySQL To Hdfs-阿里云开发者社区

环境: Hadoop2.7.2(NameNode HA,ResourceManage HA)

1.下载
[root@sht-sgmhadoopnn-01 hadoop]# wget http://apache.mirrors.tds.net/sqoop/1.99.6/sqoop-1.99.6-bin-hadoop200.tar.gz
[root@sht-sgmhadoopnn-01 hadoop]# tar -zxvf sqoop-1.99.6-bin-hadoop200.tar.gz
[root@sht-sgmhadoopnn-01 hadoop]# mv sqoop-1.99.6-bin-hadoop200 sqoop2

2.配置环境变量
[root@sht-sgmhadoopnn-01 ~]$ vim .bash_profile
添加如下内容：
export SQOOP_HOME=/hadoop/sqoop2
export CATALINA_HOME=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs
export PATH=$SQOOP_HOME/bin:$PATH
保存退出即时生效：
[root@sht-sgmhadoopnn-01 ~]source .bash_profile

3.配置服务端
[root@sht-sgmhadoopnn-01 hadoop]# cd server/conf
[root@sht-sgmhadoopnn-01 conf]# pwd
/hadoop/sqoop2/server/conf
[root@sht-sgmhadoopnn-01 conf]#

[root@sht-sgmhadoopnn-01 conf]$ vi catalina.properties
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/hadoop/hadoop/share/hadoop/common/*.jar,/hadoop/hadoop/share/hadoop/common/lib/*.jar,/hadoop/hadoop/share/hadoop/hdfs/*.jar,/hadoop/hadoop/share/hadoop/hdfs/lib/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/yarn/*.jar,/hadoop/hadoop/share/hadoop/yarn/lib/*.jar,/hadoop/hadoop/share/hadoop/httpfs/tomcat/lib/*.jar
###添加集群环境的本机的jar的目录

[root@sht-sgmhadoopnn-01 conf]$ vi sqoop.properties
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/hadoop/hadoop/etc/hadoop

4.添加mysql driver
[root@sht-sgmhadoopnn-01 conf]$ cd /hadoop/sqoop2/server/lib
[root@sht-sgmhadoopnn-01 lib]# rz

#####创建job对象,这个别写错了，使用LINK ID,而不是 Connector Id
#####使用这两个link Id来关联job的From和To部分。说的通俗一点，就是我们需要从哪里(From)读取数据,把这些数据导入(To)到哪里
